Photosynthesis Powerpoint

For this assignment, we were instructed to create a powerpoint presentation of at least 12 slides that adequately covered an academic subject of our choice. All sources for media is cited in the work cited at the end of the presentation.

Photosynthesis Powerpoint

  1. 1. Photosynthesis<br />Nick Gotshall<br />
  2. 2. What is Photosynthesis?<br />Takes Place in Plant’s Leaves<br />Series of Reactions in Plant Cells <br />Conversion of Light Energy<br />Provides Chemical Energy<br />Base of Almost All Food Chains<br />
  3. 3. The “Typical” Plant Cell<br />Eudicot<br />Genetic material <br />membrane bound organelles<br />Cell Wall<br />Vacuole<br />Chloroplasts<br />
  4. 4. Overall Reaction<br />CO2 + H2O sunlight Sugar + O2<br /> Chlorophyll<br />Chlorophyll and sunlight must be present<br />Takes place in a series of two reactions<br />Light reaction=first<br />Calvin Cycle=second<br />
  5. 5. Light Reaction<br />Dependent upon presence of sunlight (photons)<br />Takes place in chloroplasts (thylakoid)<br />Transfers Electrons in four reactions<br />Overall Reaction <br />H2O sunlight/chlorophyll O2 + ATP + NADPH<br />
  6. 6. Light Reaction Continued<br />Produces …<br />Oxygen (O2)<br />Chemical Energy to fuel Calvin Cycle<br />ATP<br />NADPH<br />
  7. 7. Calvin Cycle<br />Takes place in chloroplasts (stroma)<br />Formerly “Dark Reaction”<br />Does not require photons<br />Requires products of light reaction<br />Produces usable energy in series of reactions<br />Sugar<br />
  8. 8.
  9. 9. Importance of Photosynthesis<br />Provides base for almost all food chains<br />May have been initial means for evolution<br />Waste from photosynthesis is oxygen<br />Leads to increased biodiversity<br />
  10. 10. Human Uses for Plants<br />Food<br />Raw materials <br />Fuel<br />Clothing<br />Currency<br />The List is endless!<br />
  11. 11. Review; Photosynthesis…<br />Takes place in plant’s leaves<br />Happens in chloroplasts in plant cell<br />Photosynthesis converts photons into sugar<br />Light reaction<br />Dark reaction<br />Very important for everyone!<br />
  12. 12. Work Cited<br />Slide 2<br /> Leaf- 2003-01-05.<br />Slide 4<br /> under the horsechestnut tree enjoying peace and quiet <br />Slide 8<br /><br />Slide 10<br /> Fruits and Colors.<br />
